Add more descriptive types to the data dictionary

[foster33]

This PR closes NationalSecurityAgency/datawave#708

Depends on NationalSecurityAgency/datawave-type-utils#34

The data dictionary page previously showed "Unknown" for data types that were not in its list of datatypes.

This PR adds:

• Use of a class defined data dictionary description for 'Types'
• Adds some new test cases

See #23 for more background information and discussion about these changes.
This is the same as #23 . It was accidentally closed when I deleted my fork.

I am not sure if this ticket is related or if there is another ticket to this issue, but there also seems to be weird lastUpdated entries where the dates contain a '+' value. It seems like they are newly added.

It does not seem like the changes in this PR are causing that. I do see what you mean. I tested to see if it would happen with the latest changes with "main" and still get the occasional timestamp with "+". It seems to only affect fields that include _TOKEN. Trying to debug this now. But I will open an issue about this in the meantime.
